SHUTTLE-MOVEB. I

Application filed November 29, 1920. Serial No. 427,107.,

To all whom it may concern:

Be it known that I, FRANK Josnrn BAUME, a subject of Alsace-Lorraine, and a residentof Mulhouse, Alsace-Lorraine, have invented certain new and useful Improvements in Shuttle-Movers, of which the following is a specification.

My present invention relates particularly to shuttle moving means of looms, and aims to do away with the usual means actually in engagement with the shuttle for moving the same and to bring about various advantages not only in construction of looms but in construction of shuttles, by the application of shuttle moving means which will effect the desired results as far as movement of the shuttle is concerned without actually engaging therewith.

In the accompanying drawings which illustrate my present invention and form a part of this specification,

Figure 1 is a detail side view illustrating the parts proposed by my invention,

Fig. 2 is a bottom plan view of a shuttle of one construction,

Fig. 3 is a detail side view of a portion of a shuttle and its race-Way adjacent to one end of the latter,

Fig. 4 is a vertical transverse section taken substantially on line 44* of Fig. 1,

Fig. 5 is a view illustrating a modified form of electro-magnet and carriage,

' Fig. 6 is a detail perspective v1ew of a shuttle race-way of one form, and

Fig. 7 is a detail perspective view of a portion of a shuttle race-way of another form.

Referring now to these figures my invention roposes the use of a shuttle 10 which may be of various constructions and of ma terially less complication than shuttles at present used which are engaged at their ends by the means serving to move the shuttle in operation, the only requirement of my invention asregards the shuttle be ing that it shall be constructed either in part or in whole of magnetically attractable material. The most simple form of this arrangement and the one possibly to be preferred is the shuttle shown in Figs. 1, 2 and 3 whose body may be formed of-any material having attached lengthwise upon its base a centrally disposed strip 11 of magnetically attractable material, the body hein for instance formed of wood and the strip 11 secured thereto by attaching screws I Specification of Letters Patent.

Patented Apr. 5, 1921 12. In this instance the loom with its lower strip 11 forms its own guide in the race-way 13 of a lay having a lengthwise slot 14, in which the strip 11 moves to prevent lateral displacement of the shuttle.

flanges 15 but is preferably without such flanges as seen in Fig. 7 in particular so that by providing the surface of the raceway with transverse grooves,the latter may receive warp threads and in this way permit the shuttle to move over such threads as are disposed in the grooves, without touching the same. The ends of the raceway may be provided with upright flanges 16 as in Fig. 3 carrying shock absorbmg springs 17 with which the ends of the raceway may contact, and it is obvious from the foregoing that with the shuttle strip 11 exposed to the space below the race-way through its slot 14 and the race-way itself formed of non-attractable material, the shuttle may be controlled in its movement by a lower'electro-magnet 18 which I have shown in Figs. 1 and 4 as mounted upon a carriage 19, the latter having rollers 20 arranged in vertically opposing pairs at opposite sides of its front and rear portions to engage the upper and lower surfaces of spaced parallel tracks 21, this construction preventing movement of the electro-magnet 18 either toward or away from the shuttle by arranging the tracks 21 parallel With and below the race-way 13 as it 1s proposed to do. A permanently spaced relation between the elcctro-magnet and the shuttle is thus brought about so that by maintaining proper electrical connections with the windings 22 of the electro-magnet, uniformly efficient operation can be maintained.

In instances where it is not possible to utilize the electro-magnet upon a carriage 19, the electro-magnet itself, indicated generally at 23 in Fig. 5 may be provided with a depending portion 2%, preferably in sulated therefrom and provided with rollers 25 similar to the before described rollers 20, engaging tracks 26 positioned and constructed like the tracks 21.

My invention does not contemplate any particular manner of moving the electromagnet with its carriage as a number of different connections may be made with the moving parts of the loom depending upon the particular type of the loom, for bringm this movement about, and the choice 0 The raceway may be provided with upright side means for this purpose is obviously not limited by any means such as the choice is limited at the present time 1n connection with shuttle engaging means for moving the shuttle.

I claim:

1, In looms a shuttle having a lower lengthwise strip of magnetically attractable material, a race-way on which the shuttle is movablehaving a lengthwise slot into which the .said strip of the shuttle projects for guiding the shuttle, a track parallel with and below the race-way, and a carriage movable in guided relation on the track and having electro-malgnetic means spaced below the race-Way to attract the shuttle.

2. In looms, a shuttle having a lower lengthwise strip of magnetically attractable material, a lengthwise slotted raceway on which the shuttle is movable having transverse surface grooves to receive warp threads, and into the slot of which the magnetically attractable strip of the shuttle extends and forms a guide, and electro-magnetic means having guided movement parallel with and spaced below the race-way for attracting the shuttle.
